i bought new ZK6000 model fingerprint scanner and im using FFV SDK. When i try to run the sample its showing "enrollment has not finished reason no scanner" error. Kindly help .

Hello,

What drivers have you installed? We always recommend to isntall drivers provided with SDK that could be found at "FreeFingerprintVerificationSDK\install\Fingerprint Scanners\ZKSensor6000".Please also make sure there is FPSmmZKSensor6000.dll in "FreeFingerprintVerificationSDK\bin\Win32_x86\fpsmm\" directory.

Hello,

please try to kill DPHost and iZHost processes.For what purpose are you going to use the FFV SDK? Actually this SDK is very limited and if i.e. you will need to enroll more then 10 persons, it will not be possible with the FFV SDK.

Failed to intialize nffv or create/load db failed. pl chk....

Wat might be the problem. in going to use it a billing system. The number of user will be 3 or 4

please check if the NffvServer is unloaded from precesses. If it is not unloaded, then on next load of the application scanners will not be found and error will be thrown.Actually I would recommend to use VeriFinger 6.3 SDK. FFV SDK is an old one and it is not updated very often. Therefore there can be issues with its usage on new operating systems like Windows 7.

I've tried to delete all Fpsmm*.dll files except FPSmmIdentix.dll in Fspmm, (wich I have copied from Additional to Fpsmm) , same error

The DFR2100 works fine in the demo software from L1-id.

Help will be very much appreciated.

Hi,

the DFR-2100 scanner returns the scanned image, only when the fingerprint is removed from the scanner. So in your case you need to put a finger shortly on the scanner and remove it after short period of time.

Hello, I have Suprema BioMini scanner. It is in the list of supported scanners of Free Fingerprint Verification SDK, but i got an error "Enrollment failed.reason: No scanner" I use Sup_Fingerprint_Driver_V2.0.2 and FFV SDK downloaded from neurotechnology.com

Hello,

please use drivers, provided with the FFV SDK. They are in folder "install\Fingerprint Scanners\Suprema" of the downloaded SDK.

Hello, thanks for reply.I use Suprema BioMini SFR-410 (A), drivers from "install\Fingerprint Scanners\Suprema" are not suitable.Think that problem is not in drivers, because demo program from suprema get fingerprints from my scanner with no problems.

The FFV SDK supports Suprema BioMini 400 (A), not the 410 (A). The Suprema BioMini 410 (A) is supported in latest version of the VeriFinger 6.6 and MegaMatcher 4.4 only.

Hello,

could you please provide the detailed description of the issue you are receiving?

Hello,

Could you please be more specific and explain in more detail what do you mean?The database is used to store fingerprint template and the user name. Password is used if you want to protect your database.

Hello,

Please make sure you have Nffv.dll, NffvJavaNative.dll, NffvServer.exe and Nffv.jar at the same directory where your application startup path is.

Hello,

The FFV SDK has been developed and introduced quite long time ago. Due to recent changes in Java security policy, it does not allow to copy some files to some locations.The Java Applet in the FFV SDK, requires that files from the SDK would be copied into “C:\Users\<username>\.neurotec\Nffv” folder. So to be able to run the Java applet you need to copy the files listed below from “win32_x86” folder to this folder.

I bought and installed U.are.U. 4500 fingerprint scanner and installed the drivers for it. Then I installed and ran FreeFingerprintVerificationSDKinWin32_x86CSharpSample

When I click on "Enroll" button I get prompted for a "Name" and when I enter something I get an error message "Enrollment was not finished. Reason: NoScanner"

Yet, when I go to computer settings I can see that the drivers for the fingerprint scanner are installed and it says device is working properly.

Hello,

What drivers have you installed? Where did you get them from?You need to install the drivers provided with the SDK: "FreeFingerprintVerificationSDK\install\Fingerprint Scanners\UareU". So please uninstall the drivers that are installed currently, and install the ones provided with SDK. Note, make sure you reboot computer when it asks for that.

first thanks for you to accept my new account,my question " i try free C Sharp example in Free Fingerprint Verification SDK 1.0 sample program and i try to use c# sample code in visual studio 2010 , when i run the visual studio first form is choosing fingerprint reader devices ,so i haven"t any fingerprint reader ,i want to get the fingerprint image(enroll ) from file or database to enroll the fingerprint image not from fingerprint reader "please help me i have final project in fingerprint recognition in my collage so can you give me steps or simple additional code to get the finger image from database or filei thanks you for your advice ,i will wait for your reply.thanks .

Hello,

Free Fingerprint Verification SDK is limited SDK and it does not allow to extract templates from images or retrieve templates from the database.Such possibility is available in the VeriFinger and MegaMatcher SDKs. 30-day trial version can be downloaded from our website.

marwankhiled wrote:if i use VeriFinger and MegaMatcher SDKs can i run programe without finger reader can get finger image to be insert in thes programes without using finger reader<thanks for reply me>

Hi,

yes you will be able to use these SDKs without fingerprint scanner. Both SDKs provides the API to extract fingerprint template from the image.

thanks to you,advice me 1- what database type can i use to save fingerprint image that comfortable or associated with verifinger SDK Trial 2- what fingerprint template format that can i used to save fingerprint template inside database3- can i get these fingerprint image directly in what format 4- is it important to convert fingerprint image in specific format to allow me to save it in the database

marwankhiled wrote:what database type can i use to save fingerprint image that comfortable or associated with verifinger SDK Trial

VeriFinger Standard SDK can be used with any kind of the database you want. You will need to implement the communication with the database by yourself.VeriFinger Extended SDK includes a ready-to-use matching server (NServer) and if you will choose to use ti then the you will need to use one of these databases: MSSQL, MySQL, Oracle, postgreSQL.

marwankhiled wrote:what fingerprint template format that can i used to save fingerprint template inside database

We are using our proprietary format of the template. It can be saved as byte array for the insertion into the database.It is possible to convert proprietary templates to standard templates if the Finger Client license is available.

marwankhiled wrote:can i get these fingerprint image directly in what format

It depends on the license used. Finger Extractor license supports almost all image formats, except the WSQ, JPEG2000 and IHead, which support is enabled with the Finger Client license.

marwankhiled wrote:is it important to convert fingerprint image in specific format to allow me to save it in the database

As it was mentioned above the matching is done with templates not images. So you can save image in any format you have selected.

Hello,

Trial version of the SDK requires permanent internet connection. You could not use trial version of the SDK without internet connection.
